SINCLAIR J. JOHNSON, OF NEl/V YORK, N. Y.

DUMPING-CAR.

SPECIFICATION forming part of Letters Patent No. 571,483, dated November1'7, 1896.

Original application filed February 24, 1896, Serial No- 580,55'7.Divided and this application filed July 25, 1896. Serial No, 600,479.(No model.)

T 0 on whom it may concern:

Be it known that I, SINCLAIR J. JOHNSON, a citizen of the United States,and a resident of the city of New York, in the county and State of NewYork, have invented certain new and useful Improvements in Dumping-Oars,of which the following is such a full, clear, concise, and exactdescription as will enable others skilled in the art to which myinvention ap pertains to make and use the same, reference being had tothe accompanying drawings, forming part of this specification.

My invention is applicable for use upon hopper-bottom gondola cars,ore-cars, and some other styles of dumping-cars It has for its objectthe combination, with the gate which closes the exit for the load, of

mechanism for opening and closing the same, so as to avoid some of thedifficulties heretofore experienced, and afford a more convenient meansfor holding the gate open or closed; and the invention consists of theparts and combinations hereinafter more fully described, and pointed outin the claims.

This application is a division of one filed by me on February 24,1896,Serial No. 580,557.

The drawings illustrate the invention in combination with ahopper-bottom gondola car having an oscillating gate, as more fullyshown and described in an application filed by me on even date herewith,Serial No. 600,480, but it will be understood that the improvement isapplicable to other styles of gate.

In the drawings, Figure 1 is a side view of a portion of a hopper-bottomgondola car having its hopper provided with a gate suspended by twohangers pivotally connected at each end and showing the mechanism foropening and closing the same in the position assumed when the gate isclosed. Fig. 2 is a similar View showing the gate open and the mechanismin the position assumed at such time.

In the drawings, A represents the side sill, and B the hopper, of ahopper-bottom gondola car, in which the load passes out at the bottom ofthe hopper when the gate 0 is open. All cars are not, however, providedwith a hopper, technically so called, and hence this word is used in abroad sense for the pur pose of designating thereby the part of the carwhich is provided with an exit for the load and which exit is opened orclosed by the gate.

The gate 0 is shown in the drawings as being suspended from the car bystraps or hangers b I), pivoted at their upper ends to the side sill Aby bolts to a passing through the same, or by passing through plates a aand the side sill, or in any other suitable way. These hangers, asshown, are also pivotally connected with the opposite edges of the gateby bolts or pivots c 0, so that the gate may be made to oscillate on thepivotal connections whep being opened or closed, though this movement isnot essential to the operation of the mechanism for opening and closingthem. Such mechanism is operated by a shaft secured to the gate or tothe car and having lever connections therewith.

A shaft e is secured at each end of the gate 0, underneath the same, byan iron h, or it may be secured on the hopper or a portion of the car,and preferably extends the length of the gate to receive the leverconnections at each end for opening and closing. Each end of the shaft,or, if desired, a separate piece at each end, forms projections or barst' along or near the ends of the gate and crosswise thereof, and thesebars are pivoted at their outer ends to another bar 71, a knuckle-jointbeing preferably formed at such union. The bar 1" is in like mannersecured by ashaft or pivotal connection 6, held in place by an iron orconnection h. I prefer also to provide a rest 7& in such a position onthe hopper that the knuckle-joint when the gate is closed will be on orbelow the line of dead-center of the pivot-points of the shafts e and 6,so asto make a secure fastening. One of the levers or bars 2 or 2" mayalso be provided with a handle j for operating the same, though this canbe done by taking hold of one of the bars.

As seen in Fig. 1, the gate is closed and the bars '5 and 'i are foldedtogether. The opera tion of opening consists in separating the bars soas to cause the gate to swing away from the exit, and this is effectedby swinging the bars up and over, so that they become spread, and whenthe limit of movement allowed by the knuckle-joint is reached they willform practically one continuous bar, held at one end by one of theshafts or pivotal connections 6 or 6, While the other has changed itsposition and moved the gate with it until open. A reverse movement andfolding of the bars together will close the gate.

It is obvious that various applications of the mechanism for opening andclosing the gates may be made to different styles of gate fordumping-cars and that changes may be made in the details andarrangements of parts Without departing either from the spirit orsubstance of my invention.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. In a dumping-car, the combination of a gate adapted to close the exitfor the load, a lever-arm having one end pivotally secured on the underside of said gate, a second leverarm having one end jointed to the outerend of the first, and the other end pivotally secured on the under sideof the car, said leverarlns being adapted to be spread and open the gateand to be folded and close the same.

2. In a dumping-car, the combination of a gate adapted to close the eXitfor the load, a shaft having its bearings on the under side of saidgate, a lever-arm projecting from said shaft, a second lever-arm jointedto the outer end of the first and pivotally secured at its other end 011the under side of the car, said lever-arms being adapted to be spreadand open the gate, and to be folded and close the 831116- 3. In adumping-car, the combination of a gate suspended by hangers adapted tooscillate in opening and closing the exit for the load, a lever-armpivotally secured to said gate, a second lever-arm jointed to the outerend of the first and pivotally secured at its other end on the underside of the car, said lever-arms being adapted to be spread and open thegate and to be folded and close the same.
